AVK Innovation Award 2022 to young engineers from ITM at TU Dresden

  • Award for near-net-shape 3D meshes for use in fibre-reinforced plastics

As part of the JEC FORUM DACH 2022, the AVK Innovation Awards were presented in Augsburg on November 29th. The innovation price in the category "Research/Science" (first place) was awarded to the team of scientists Dipl.-Ing. Dominik Nuss, Dr.-Ing. Cornelia Sennewald and Prof. Dr.-Ing. habil. Chokri Cherif.

With the development of the pull-off-free Jacquard weaving technology including the technological know-how in the field of highly complex 2D and 3D fabric geometries, which has been established at the ITM of the TU Dresden for many years, Dominik Nuss has succeeded in including different yarn lengths locally into the fabric structure solely through targeted variation of the fabric weave. There-fore, it is now possible to produce completely new types of fabrics without additional draping, especially spherically curved fabrics, but also large-format spiral or even curved fabrics. The fact that the required near-net-shape geometry of the component to be reinforced can be reproduced with significantly reduced preforming steps is to be emphasized.

Continuous simulation aided engineering from CAD design to integrally woven 2D and 3D preforms by means of highly complex weave development for spatial constructions is a unique at the ITM, which was indispensable for the development of these promising woven high-tech structures. This technology is completely new and has never been carried out in this way before. The fabric structures are characterised by a high innovation level due to their geometric diversity and purposes. It can be used in numerous applications and further more contributes to the development of completely new fields of application. The technology can be implemented on all Jacquard weaving machines with only an additional device and the preform geometry is only determined by the control of the Jacquard machine. The preform geometry can be used in the full working width of the weaving machine.

Professor Chokri Cherif, Institute Director of the ITM, and his team are very pleased about these continuous research success in the constantly growing research field of 3D weaving technology, which are achieved at the ITM in close cooperation with industry and users. "This award is a special honour for our institute and confirms that the many years of our excellent research in the field of near-net-shape 3D weaving for the fibre-reinforced plastics sector plays a significant role and that we are making a significant contribution to the sustainable and resource-efficient production of lightweight structures with our development".

Award for best master's thesis of the German Textile Mechanical Engineering 2022 goes to young engineer of ITA Aachen

The 2002 prize of the Walter Reiners Foundation of the VDMA Textile Machinery Association for the best Master's thesis in German textile mechanical engineering was awarded to a young engineer from the ITA Institut für Textiltechnik of RWTH Aachen University. The prize ceremony took place at Techtextil 2022 in Frankfurt am Main, Germany. Peter D. Dornier, Chairman of the Board of the Walter Reiners Foundation, presented the award at the VDMA Textile Machinery Association’s booth.

Felix Xaver Zerbes, M.Sc., was awarded the "Promotional Prize for the Best Master's Thesis of the German Textile Machinery Industry 2022", endowed with 3,500 EUR, for his master's thesis "Development and Construction of a Separation Unit for Weft Yarns in Air Jet Weaving".

The subject of the master's thesis was the development of a mechanism with which faulty sections in the weft yarn can be sorted out before they are woven into the textile. This way, both yarn-related weft defects and material defects can be drastically reduced. The prototype developed by Mr Zerbes shows how this can be done even during the ongoing weaving process without having to stop production. Due to its modular design, the yarn rejection unit can be retrofitted to many different types of air-jet weaving machines, which represents an enormous savings potential not only in Germany but in weaving mills all over the world.

Innovate or die: TMAS at ITMA 2019

A focus on customer service, aligned with the drive to constantly innovate, has long ensured that the member companies of TMAS – the Swedish texile machinery manufacturers’ association – stay well ahead of the curve.

“All of the Swedish textile machinery companies are doing really well in major markets such as Europe, China, India and the USA,” says TMAS Secretary General Therese Premler-Andersson. “They are now gathering forces to prepare for the most important show – ITMA 2019 in Barcelona in June. I expect to see new players and partnerships as we enter the industry 4.0 era for real. We are ready to display an even higher degree of the real time monitoring of processes, automation, flexible customisation, and the incorporation of robots into production lines.  Our customers expect a lot of in terms of knowledge and our ability to customise and offer turnkey solutions.”

A focus on customer service, aligned with the drive to constantly innovate, has long ensured that the member companies of TMAS – the Swedish texile machinery manufacturers’ association – stay well ahead of the curve.

We are ready to display an even higher degree of the real time monitoring of processes, automation, flexible customisation, and the incorporation of robots into production lines.  Our customers expect a lot of in terms of knowledge and our ability to customise and offer turnkey solutions.”

The forward-looking attitude of the Swedish companies is perhaps best summed up by Reimar Westerlind, the owner, since 1961, of ACG Gruppen.
At the age of 90, Reimar still travels to his office every day to oversee the operations of the diverse companies operating under the ACG umbrella.
“Everything now is about automation and digitisation,” he says. “We have to be on that track or we will be lost – innovate or die.”

Robotics
One ACG Gruppen company moving rapidly forward with new innovations in this area is ACG Kinna, which at ITMA 2019 will be providing dramatic live demonstrations of its new robotic pillow filling system.
This has the ability to fill and finish some 3,840 pillows per eight-hour shift, which is a considerable improvement on what is currently possible with existing systems, resulting in significant savings in both labour and energy for busy home textile businesses.

At ITMA 2019, Eton will be demonstrating a complete material handling solution with advanced software providing real-time information covering every aspect of the process.
“Our systems are a natural fit with the major Industry 4.0 networked manufacturing plants that are now being constructed worldwide for sectors such as the garment and home textiles manufacturing and automotive industries,” says Eton’s Sales and Commercial Director Roger Ryrlén.

Sensors
Advanced senor developments are playing a large part in moving many areas of the textile industry forward too.
Eltex of Sweden, for example, is achieving considerable success with its yarn fault detection and tension monitoring systems across a range of sectors, including the tufting of carpets, the creeling of woven materials and even the production of woven reinforcements for the composites industry.

At successive ITMA shows, IRO AB has also consistently introduced new milestones in the field of yarn feeding technology for weaving machines, and ITMA 2019 will be no exception.
“Following significant investment in our R&D capabilities, we have been making great progress in further boosting the efficiency and performance of our expanding X3 range,” says IRO AB Managing Director and Chairman of TMAS Mikael Äremann. “I can’t remember a time since the 1980s when we had so many new innovations to unveil at an ITMA, and I’m greatly looking forward to the positive response to them we are anticipating in Barcelona this June.”

Resource savings
ITMA 2019 will meanwhile see the launch of TexCoat G4 – the next generation of Baldwin Technology’s non-contact precision application system for fabric finishing. The TexCoat G4 enables a continuously high-quality and productive textile finishing process with zero chemistry waste and minimised water and energy consumption.
The non-contact spray technology brings a range of advantages including single or double-sided application,  the elimination of Foulard bath contamination, low wet pick-up levels leading to the elimination of drying steps, zero chemistry waste in changeovers of chemistry, colour or fabric, and the possibility of batch reporting, visibility of pad loading, chemical usage etc.

Other TMAS companies exhibiting in Barcelona include Texo AB, whose wide-width weaving looms make the belts for machines on which half of the world’s paper is made, ES-Automatex, which specialises in bespoke automation concepts and Svegea, a company leading the field in a number colarette machines and cutting and slitting equipment.

“At the last ITMA in 2015 in Milan, there was much talk about Industry 4.0 technologies but certainly from the perspective of TMAS, ITMA 2019 will be the place for concrete solutions as to how data and the new tools we have available can be exploited to the full,” says Therese Premler-Andersson. “There is already much more networking between the companies, with software very much the enabler and common interfaces bringing ideas closer together. We are greatly looking forward to further exchanges of ideas when meeting with customers old and new in Barcelona.”
